provide a wringer equipped with a feed an'd aving parts so constructedand arran ed that the said device can be easily and rea ily adjustedfromfone side to the other of the wringer.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various 'parts of mywringer safety feeder, whereby 2 the objects*l contemplated areattained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanymg drawings, in which:

Figure 1 is a top or plan view of a wringer equipped with a safet feederembodying my invention, one end of t e wringer being shown in horizontalcross section.

Figure 2 is a'detail, sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a detail, sectional view taken on the line 3-3 of Figure 1;and

Figure 4 is an enlarged, detail, sectional view illustrating the meansfor locking the spindles in their notches or slots.

In the. accompanying drawings, I have shown a wringer which may be ofthe type now commonly used, having the lower lon itudinal memberindicated in the drawin s y the reference numeral 10 and the spaceopposite end members 12.

A lower wringer roll 14 has a shaft 15 journaled in the end members 12and provided at' one end with gearing mechanism 16, through whichrotation maybe imparted to the roll 14.

Pivoted. to the frame members 12 at the top thereof are the arms 18. Thearms 18 are connected by a cover strap 20.

A release member in the form of a connecting cover 22 has at its endsthe arms or fingers 24 pivoted to the arms .18 near their free ends. Therelease 22 coacts with hook members 26 for locking the upper wringerroll 28 in position. l

The wringer roll 28 has the shaft 30 journaled in the arms 18.

The structure above described is standard and forms no part of mypresent invention, except that the upper 'wringer roll 28 of the wringerused with my safety feeder, should .be capable of being movedupwardlyfzand substant'ially away from the roll 14.i

In Figure 3, I have shown in dotted lines the upper roll swing upwardlyand out of the 'Xhe wringer is also'provided at each end and near itsopposite sides with lu s 32, having slots 34 in their upper ends. heselugs are for supporting the feeder.

-My improved feeder comprises a channelshaped member 36 having the insetend walls 38. The walls 38 have near their upper and lower partsprojecting spindles 40.

The two lower spindles 40 are dropped into the slots 34 of the lugs 32at one side of the 75 wringer. Each end member 38 has midway between itsspindles 40 a lug 42, extending lolgitldinally outwardly. (See Figures 1an 3.

In order to hold the spindles 40 in the slots 34, I have provided in thelugs 32, spring actuated pins 60 with rounded inner ends, past which thespindles 40 can be forced. The pins 60 serve to hold the spindles 40 inplace, 85 as illustrated for instance 1n Figure 4, against accidentalremoval. y

For connectin the feed with the lower wringer roll, an thus providingmeans for actuating the feeder, I provide the following means:

On the shaft 15 of the lower wringer roll 14 at each end of the roll isfixed an eccentric disc 44. A band or ring 46 is received on the disc 44and has a projecting arm 48 terminating in the reduced portion 50, whichis slidablye'xtended through the lug 42, as shown in Figure 1.

On the reduced portion 50 is a coil spring 52, which is held against thelug a cotter pin or the like 54, extended through the outer end of thereduced portion 52.

Referring now to Figure 3, it will be seen that when the lower wringerroll is rotated, the eccentric disc 44 will give to the band 46 and thearm 48 a reciprocating motion. This will be transmitted to the lugs 42and thus to the wr'inger feeder.

The wrihger feeder -will thus be rocked upon its lower spindles 40 fromits position shown in Figure 3 to the position shown in Figure 2 andback.

In feeding the garments to the wringer, the garments are laid over theupper part of the member 36, when that member is at its outer position,as illustrated in Figure 3. Then as the roll 14 rotates, the feeder willbe rocked to the position shown in Figure 2, where the upper partthereof will stand in the position shown in Figure 2 for feeding 'thegarments to the wringer rolls.

When the feeder is rocked back to the positionshown in Figure 3, anothergarment can be laid on it to be fed to the wringer.

If it is desired to change the feeder from one side of the wringer tothev other, the upper wringer roll is released and swung upwardly out ofthe way by the standard mechanism, and the feeder is swung upwardlyacross and part way around the lower wringer roll, from its full lineposition show n in Figure 3 to its dotted line position shown in thatfigure.

The spindles 40, which were the upper spindles when the feeder was onthe left side of the wringer, as shown in Figure 3, will after thechange be received in the slots 34 of the right-hand lugs 32, and whenthe upper roller is again replaced in position as shown in Figure 3, thefeeder can b e used on the right-hand side of the wringer.

It will be seen that there is thus provided a feeder, the upper part ofwhich rocks or reciprocates toward or from the line between the twowringer rolls.

The feeder is actuated by the operation of the wringer rolls themselves.It may be conveniently swung from one side of the w ringer to the other.

The importance of awringer safety feeder will be readily seen. Itfrequently occurs that during the wringing operation. the hand of theoperator is caught in the wringer roll and seriously crushed or mangled.This is a danger which becomes more important on account of the factthat wringers are now operated by power.

Wlith a device of the kind shown here, the danger of catching theoperators fingers or hand is very largely eliminated` I have in thedrawings herewith illustrated one form in which my wringer safety feedermay be embodied. It is not my purpose to limit myself to that particularform of feeder, nor to the particular mounting or manner of operationherein set forth, but it is my purpose to cover by my claims anymodified forms of structure or use of me-y chanical euivalents, whichmay be reason- .3 1
